Problems solved by technology

[0004] At present, due to factors such as equipment, technology, and cost, there are relatively few studies on waste glass asphalt mixture in my country, and there is a lack of comprehensive and systematic understanding of the performance of waste glass asphalt mixture, which makes it difficult to implement in road engineering practice and has not been popularized and sustained. application

preparation example Construction

[0023] The preparation method of the present invention comprises the following steps:

[0024] 1) Put the waste glass into a pulverizer for crushing, and sieve and analyze after crushing, and separate the particles with a particle size greater than 4.75mm and less than or equal to 16mm as the coarse glass aggregate, and the particles with a particle size greater than 0.6mm and less than or equal to 4.75mm as the Fine glass aggregate;

[0025] 2) First, wash the coarse glass aggregate and fine glass aggregate in pure water and filter out residual impurities, and then separate the coarse glass aggregate and fine glass The aggregates are soaked in pure water for 60-120 minutes, and finally placed in a constant temperature drying oven to dry for later use;

[0026] 3) Heat the base asphalt to a liquid state, add TPS modifier and mix, then add coarse glass aggregate, fine glass aggregate and mineral powder in turn, and mix to obtain asphalt mixture.

Embodiment 1

[0028] Take 1000g of asphalt mixture as an example, the raw materials and their dosage are: 179.8g of SK-90# base asphalt, 359.5g of coarse glass aggregate, 197.7g of fine glass aggregate, 236.0g of mineral powder and 27.0g of TPS modifier; parts by mass As follows: 8.0 parts of SK-90# matrix asphalt, 16.0 parts of coarse glass aggregate, 8.8 parts of fine glass aggregate, 10.5 parts of mineral powder, and 1.2 parts of TPS modifier.

[0029] SK-90# base asphalt is provided by Guangzhou Lubao Asphalt Co., Ltd.; the particle size of waste glass aggregate is greater than 0.6mm and less than or equal to 16mm; among them, the coarse glass aggregate is waste glass with a particle size greater than 4.75mm and less than or equal to 16mm, and the fine Glass aggregates are glass powder chips with a particle size greater than 0.6mm and less than or equal to 4.75mm; aggregate A with a particle size greater than 4.75mm and less than or equal to 9.5mm and aggregate B with a particle size gre...

Embodiment 2

[0065] Take 1000g of waste glass asphalt mixture as an example. The raw materials and their dosage are: 181.9g of SK-90# base asphalt, 363.6g of coarse glass aggregate, 181.9g of fine glass aggregate, 242.4g of mineral powder, and 30.2g of TPS modifier; The mass parts of the above raw materials are as follows: 6.0 parts of SK-90# matrix asphalt, 12.0 parts of coarse glass aggregate, 6.0 parts of fine glass aggregate, 8 parts of mineral powder, and 1 part of TPS modifier.

Abstract

The invention discloses a bituminous mixture doped with glass aggregates and a preparation method thereof. The invention aims to prepare a mixture having the advantages of excellent deformation performance and thermodynamic performance and high water stability and high-temperature stability, so as to increase the use ratio of the waste glass and protect the environment. The bituminous mixture comprises the following materials in parts by weight: 6.0-10.0 parts of matrix asphalt, 12.0-20.0 parts of coarse glass aggregates, 6.0-18.0 parts of fine glass aggregates, 8.0-16.0 parts of mineral powder and 1.0-1.5 parts of a TPS modifier, wherein the grain sizes of the coarse glass aggregates are more than 4.75mm but less than or equal to 16mm; the grain sizes of the fine glass aggregates are more than 0.6mm but less than or equal to 4.75mm; and limestone mineral powder is used as the mineral powder.

Description

technical field [0001] The invention belongs to the technical field of road materials, and in particular relates to an asphalt mixture mixed with glass aggregates and a preparation method thereof. Background technique [0002] As more and more people begin to agree with the strategic goal of sustainable development, waste glass as one of industrial waste and domestic waste has begun to receive widespread attention. According to the survey, the annual amount of discarded glass in my country is 4.5-7 million tons, accounting for 3%-5% of municipal solid waste, but the recovery rate is only about 10%. Hong Kong produces nearly 120,000 tons of waste glass every year, nearly 90% of which are transported to landfills and discarded. This not only brings inconvenience to people's lives, but also occupies land, pollutes the environment, and wastes resources. How to realize the rational recycling and reuse of waste glass is an urgent problem to be solved in the current society. We ...
